Updated default Tensorflow version installed by install_tensorflow()
to 2.8.
as_tensor()
gains a shape
argument, can be used to fill or reshape tensors. Scalars can be recycled to a tensor of arbitrary shape
, otherwise supplied objects are reshaped using row-major (C-style) semantics.
install_tensorflow()
now provides experimental support for Arm Macs, with the following restrictions:
install_tensorflow()
default conda_python_version changes from 3.7 to NULL.
tf.TensorShape()
’s gain format()
and print()
S3 methods.
[
method for slicing tensors now accepts NA
as a synonym for a missing or NULL
spec. For example x[NA:3]
is now valid, equivalent to x[:3]
in Python.
Default Tensorflow version installed by install_tensorflow()
updated to 2.7
Breaking changes:
shape()
now returns a tf.TensorShape()
object (Previously an R-list of NULL
s or integers).[
method for tf.TensorShape()
objects also now returns a tf.TensorShape()
. Use [[
, as.numeric
, as.integer
, and/or as.list
to convert to R objects.length()
method for tensorflow.tensor
now returns NA_integer_
for tensors with not fully defined shapes. (previously a zero length integer vector).dim()
method for tensorflow.tensor
now returns an R integer vector with NA
for dimensions that are undefined. (previously an R list with NULL
for undefined dimension)New S3 generics for tf.TensorShape()
’s: c
, length
, [<-

(joining previous generics [

). See ?shape
for extended examples.
Ops S3 generics for tensorflow.tensor
s that take two arguments now automatically cast a supplied non-tensor to the dtype of the supplied tensor that triggered the S3 dispatch. Casting is done via as_tensor()
. e.g., this now works: as_tensor(5L) - 2 # now returns tf.Tensor(3, shape=(), dtype=int32)
previously it would raise an error: TypeError: `x` and `y` must have the same dtype, got tf.int32 != tf.float32
Generics that now do autocasting: +, -, *, /, %/%, %%, ^, &, |, ==, !=, <, <=, >, >=
install_tensorflow()
: new argument with default pip_ignore_installed = TRUE
. This ensures that all Tensorflow dependencies like Numpy are installed by pip rather than conda.
A message with the Tensorflow version is now shown when the python module is loaded, e.g: “Loaded Tensorflow version 2.6.0”
Updated default Tensorflow version to 2.6.
Changed default in tf_function()
to autograph=TRUE
.
Added S3 generic as_tensor()
.
tfautograph added to Imports
jsonlite removed from Imports, tfestimators removed from Suggests
Refactored install_tensorflow()
.
install_tensorflow(version="2.4")
will install "2.4.2"
. Previously it would install “2.4.0”)Removed “Config/reticulate” declaration from DESCRIPTION.
RETICULATE_AUTOCONFIGURE=FALSE
environment variable when using non-default tensorflow installations (e.g., ‘tensorflow-cpu’) no longer required.install_tensorflow()
for automatic installation.Refactored automated tests to closer match the default installation procedure and compute environment of most user.
Expanded CI test coverage to include R devel, oldrel and 3.6.
Fixed an issue where extra packages with version constraints like install_tensorflow(extra_packages = "Pillow<8.3")
were not quoted properly.
Fixed an issue where valid tensor-like objects supplied to log(x, base)
, cospi()
, tanpi()
, and sinpi()
would raise an error.

(#428)set_random_seed
function that makes more sense for TensorFlow >= 2.0 (#442)Bugfix with all_dims

Indexing for TensorShape & py_to_r
conversion (#379, #388)
Upgraded default installed version to 2.0.0.
Tensorboard log directory path fixes (#360).
Allow for v1

compat (#358).
install_tensorflow
now does not installs tfprobability
, tfhub
and other related packages.
Upgraded default installed version to 1.14.0
Refactored the install_tensorflow
code delegating to reticulate
(#333, #341): We completely delegate to installation to reticulate::py_install
, the main difference is that now the default environment name to install is r-reticulate
and not r-tensorflow
.
added option to silence TF CPP info output
tf_gpu_configured
function to check if GPU was correctly
